Execute does an reload when the source changes and it seaches the same
way as other pages (this is interesting for use with Embperl::Object).
Execute also only loads the module once, like use does. Execute put
every file in a different namespace.
When using with Embperl::Object, you can have the same file in different
directories and depending on the URL a differnt file is called.
